Abstract

The invention is directed to a method and a device for bending a component (71) made of a thermoplastic material, and to the component (71) itself, in particular a sleeve-shaped component having a straight shank (72), for use in a personal care appliance such as a dental care, a hair care, a kitchen apparatus or the like. A holding means (70) is provided for supporting the component (71) to be formed to shape, and the component (71) is formed by at least two tools (76, 84, 92) arranged for movement relative to each other, and a heating unit is provided for heating the component (71) in its condition as formed.
